This is a posting on behalf of a Professor Hayhurst at the University of
Lancaster, in England. Please respond to me or to the net, and I will
pass along info to him. Thanks.
Professor Hayhurst is looking for a third-party software package called
LINDO. He did not specifically say what LINDO does or is supposed to do,
so I don't know what to ask, really. All I know for sure is that he is
on a Vax running VMS, so my assumption is that LINDO is for VMS machines.
If anyone can point me in the right direction, I would appreciate that
very much. Again, thanks.

It is an interactive package, apparently written in FORTRAN, that solves linear, integer, and quadratic programming problems. As far as I know, versions are available for almost anything from the PC clones to the DEC VAX to the IBM mainframe. Copying from the LINDO user's manual (by Linus Schrage, The Scientific Press, 1981), LINDO "can optimize linear, integer, and quadratic equations with up to 4000 rows and 15000 variables." From my experiences, it is very easy to use (if you have a copy of the manual, it is even easier ;-) and has built-in help. According to the User's guide, for more information, contact: The Scientific Press, 507 Seaport Court Redwood City, CA 94063 Tel: (415) 366-2577 If you're interested, we have had LINDO running on a VAX 8300 for almost a year, and found that it works very well. (I don't believe that LINDO is ``public domain'' however, as Rick suggests.)
